/* The recommended method for sharing data for the per-core approach is as
   follows. Refer to shared.c in the Core A project for further details
   on sharing data and code.

   For Core B抯 project:
   Declare the data items as external (via extern), as they will be supplied by the
   definitions for Core A抯 project. Refer to SDRAM_CoreB.c.

   In Project Options, in the Project|Link|LDF Preprocessing dialog, define the
   macro OTHERCORE in the Preprocessor Macro Definitions field. No value need
   be supplied. It may be useful to also define the DEBUG and RELEASE macros
   for the Debug and Release configurations, respectively.

   Add a header file, local_shared_symbols.h (this file). The header file
   should re-define the OTHERCORE macro to be the pathname to the .DXE file
   produced by Core A抯 project, and include the library header
   file shared_symbols.h. */

#undef OTHERCORE

#ifdef DEBUG
#define OTHERCORE "Debug/SDRAM_CoreA.dxe"
#endif

#ifdef RELEASE
#define OTHERCORE "Release/SDRAM_CoreA.dxe"
#endif

#include <shared_symbols.h>

/* For each data item to be shared, add a RESOLVE command to
   local_shared_symbols.h, giving the symbol name and the OTHERCORE macro. */

RESOLVE(_shared_variable, OTHERCORE)
RESOLVE(_shared_function, OTHERCORE)
